There is no way to manually reset this important message from BMW alerting you of a battery issue. However, there is no need to panic as the message simply means that your battery is discharging faster than it is charging. To address this, start by disconnecting any phone chargers or other devices from the cigarette outlet and turning off unnecessary accessories such as seat heaters and the radio. Keep the engine running until the message disappears, which may take anywhere from 5 to 30 minutes. This message is commonly seen on cold mornings, particularly in regions with freezing temperatures, but it can also occur when idling at a red light. If you consistently encounter this message, especially with an older battery, it could be a sign of impending battery failure, and you should consider planning to have it replaced.

To clear the BMW warning for high battery discharge, you need to resolve the issue typically caused by a weak connection. Inspect the battery terminals to ensure they are securely linked.

A few days ago, I experienced a situation where I found the positive terminal in the trunk compartment was loose when I checked the battery connection. I tightened it, and the warning message disappeared a few days later. To be safe, I kept the battery on a trickle charger until the issue cleared up. Surprisingly, my original equipment manufacturer (OEM) battery is just a year old. Hopefully, this information is useful to you!
